UNRTE A PROCESS FOR TTING PAPER.

Application filed November 22, 1923. Serial No. 676,322.

Objects of this invention are to provide a process of treating paper, such for instance as that intended for toilet paper and paper toweling and similar purposes by which the paper is provided with a fuzz or soft coating upon its surface, to provide a process in which an exact moisture content of the paper may be secured, and to provide a process which may be very rapidly carried on at a minimum of expense.

Further objects are to provide a process of teaseling paper in which a predetermined amount of moisture is supplied the paper previous to teaseling, and to provide a method of teaseling paper which may be carried out without requiring the supervision of an operator. I

Embodiments of the invention are shown in the accompanying drawings, in which Figure 1 is a diagrammatlc View of one form of the machine for carrying out the process.

Figure 2 is a similar view of a modified form of machine.

Paper, as it is received from the finishing machine or from the'parent roll, has a relatively smooth surface and is consequently not in the most desirable form for certain purposes. It has been found also thatpapei received directly from the paper making machine does not have a uniform moisture content. Further than this, paper drawn from a parent roll is considerably drier than that supplied from the paper machine, and the extent of dryness varies, of course, with climatic changes and with the len h of time and location in which the paper 1s stored.

In practicing this process, a redetermined quantity of moisture is supp ied the paper rior to teaseling and, thereafter, the paper is roughed up so as to provide a fuzz thereon.

In the drawing, the pa er 1, as it is received from the parent r01 or from the machine, is moistened by means of a moistening roll This roll comprises a body portion provlded with a plurality of bristles 3 either of animal or vegetable origin or of metal. This moistening roller is partly submerged n water carried within the container 4. It is rotated in the direction shown by the arrow and its bristles are caused to pass by a late 5. In the passage of the bristles past t is plate they are slightly swung backward and allowed to snap forwardly and upwardly thus forming a mist of finely divided water which is thrown against the under side of the paper sheet 1. The speed of the roller and the amount of spring of the bristles may be varied to secure the exact amount of moisture desired. It has been found that this predetermined amount of moisture will very quickly soak through the paper. However, this action is hastened by passing the paper over the roller 6 against which such paper bears thus subjecting it to a small or slight kneading action and insuring the working of the water through the paper.

The paper passes from the roller 6 beneath the roller 7 and is then guided by the roller 8 to the winding drum 12 upon which the finished paper is wound.

It is to be noted that the rollers 6 and? w:

are spaced apart so as to give a taut stretch of paper freely suspended between the rollers 6 and 7. Upon the upper side of the paper a teaseling roller 9 is located, and a similar I teaseling roller 10 is located upon the under side of the paper. These rollers rotate in a direction so as to cause their periphery adjacent the papers to travel in the opposite direction from the paper as indicated by arrows in the figure. The rollers are each provided with a plurality of bristles 11 which contact with the surfaces of the paper. These bristles teasel or rough up the moistened paper and produce a fine fuzz upon the surface thereof. The correct moistening of the paper, as previously described, greatly improves this action an prevents tearing of fibers of the paper from the body portion, but instead allows these fibers to be roughed up so as to provide the necessary soft fuzzy surface.

It is to be particularly noted that by spacing the rollers 6 and 7 a material distance apart that a free stretch or freely suspended strip of paper is provided between these rollers. It is upon this free stretch of paper that the teaseling rollers operate, and it will roller 13 in the direction shown by the arrows and is wound into a roll M. The teaseling of the paper in this form is secured by means of a flexible sheet member 15 which is provided with emery or sand paper 16 on its under surface. This flexible member has one end secured to a transverse bar 17 and its other end is provided with a weight 18 to ,hold it in contact with the paper. The mechanism thus far described will teasel or form a fuzz upon one side of the aper. The other side of the paper is readily teaseled by means of a pivoted arm 19 which carries at its free end a block 20, the under surface of which, as indicated at 21, is provided with a coat of emery or sand paper. This under face bears against the outer face of the paper as it is formed in the roll 14 and thus roughens the papers and forms the soft fuzz thereon.

lit will thus be seen that a process of treating paper has been provided which will produce a soft surface upon the paper, which does not require the presence of an attendant, but which may be run continuously.

Although a few forms of the invention has been described in considerable detail,

' it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

1 claim:

1. The process of teaseling paper which naoaoea comprises supplying the paper with a predetermined amount of moistener, and producing a fuzz upon the paper after it has been moistened by striking a large number of spaced points along the surface of the paper.

2. The process of teaseling paper which comprises subjecting the paper to the action of a mist, thereafter subjecting the moistened paper to the action of a large number of strokes across'its surface and winding the paper in a roll.

3. The process of teaseling paper which comprisessubjecting the paper tothe action of a spray of finely divided water, causingthe paper to travel across an open space to provide a freely suspended strip of paper, and teaseling the surface of this suspended portion of the paper.

4.. The process of teaseling paper which comprises drawing the paper over a guiding roll, winding the paper upon a drum at a point spaced from such roll, spraying finely divided water upon the paper prior to its being wound into a roll and subjecting the moistened paper to a yielding abra sive action.

5. A. machine for teaseling paper comprising means for supplying a predetermined amount of water to the paper, a roller over which the paper is passed, means spaced from such roller for winding the paper into a roll, and members adapted to abraid opposite surfaces of such paper while it is in motion through the machine and imme diately after moistening.

Tn testimony that I claim the foregoing T have hereunto set my hand at Green Bay, in the county of Brown and State of. 'Wisconsm.
